摘要: 目的 :阐明吡喹酮治疗对血吸虫感染宿主免疫病理的影响。方法 :应用免疫组织化学和图像分析技术 ,观察日本血吸虫感染小鼠在吡喹酮治疗后肝组织内可溶性虫卵抗原 ( SEA)及抗体水平和虫卵肉芽肿的变化。结果 :治疗后 5wk,与对照组相比 ,治疗组减虫率为 98.3% ,平均肝重量和体积均显著减小 ,治愈小鼠的肝表面结节明显减少 ,组织内沉积的虫卵已钙化 ,部分虫卵肉芽肿已呈纤维疤痕样改变 ,对照组肝内仍可见慢性和少量急性虫卵肉芽肿。治疗组肝组织内抗原水平下降 ,而其抗体水平不受影响 ,肝内虫卵肉芽肿的平均直径和面积均较对照组显著缩小 ( P<0 .0 1)。结论 :吡喹酮治疗可使肝组织内 SEA水平下降 ,从而抑制了虫卵肉芽肿的病变 ,但不能逆转已形成的虫卵肉芽肿病变。

Abstract: AIM:To elucidate the effect of praziquantel treatment on immunopathology in host
in- fected with Schistosoma japonicum.METHOD:Employing immunohistochemical technique and profile
analytical technique,the authors observed the changes of antigen (soluble egg antigen,SEA) and
antibody level as well as granuloma in the liver of mice infected with Schistosoma japonicum
following praziquantel treatment.RESULTS:It was found that the number of adultworms in the
treated group was reduced by98.3per centas compared to the control group , the mean weight and volume of livers were all lesssened (P < 0. 05) at the 5th week after treatment. In cured mice, there was a significant decrease in number of egg nodules located on liver surface; the ova in the liver tissue were all calcified and some egg nodular foci became scar tissue. It was noted that the SEA level in liver tissue of the treated group decreased or even disappeared, but the antibody level showed no change; the average diameter and area of egg granuloma were significantly reduced (P < 0. 01). CONCLUSION: Praziquantel treatment could lower the SEA level in the liver tissue, and thereby inhibit the egg granuloma formation, but it could not alter the antibody level, likewise, could not reverse the egg granulomatous changes already formed
